STONIS, Andrius REMEIKIS Department of Zoology, Vilnius Pedagogical University, Studentų St. 39, LT-08106 Vilnius, Lithuania. E-mail: [email protected] Abstract. Based on the material collected by the authors in the Crimea (Karadag Nature Reserve), Aca- lyptris platani (Müller-Rutz, 1934) is recorded in Eastern Europe (Ukraine) for the first time. It represents the easternmost record of this Sub-mediterranean nepticulid species in Europe, once again confirming faunal links of southern Crimea with Mediterranean region. Adults, male and female genitalia, and leaf- mines of A. platani are illustrated and provided together with a distribution map.
